Good. Thinking more about it, the incorrect detiling explains the original
corruption, but I am not sure how the userptr test became a red herring. Anyway
problem solved.

Not an issue, should really be a warning rather than error - the present
extension won't be enabled if it doesn't exist.

Something is wrong with mesa, the call to dri2->createNewScreen() fails. Check
your build?

If you see the error from comment 12 again, please file a new bug. Thanks for
